VIBE: Calm Focus Sleep is a lifestyle app developed by Lucid Inc. for iPhone users. This free app creates personalized music mixes to help ease stress, increase focus, and improve sleep. Backed by neuroscientists, VIBE is proven to reduce anxiety and increase positivity. One unique feature of VIBE is its ability to connect with Apple Watch and use heart rate data to enhance the user's experience.

VIBE also integrates with Apple's HealthKit, allowing users to save and store their VIBE sessions as Mind & Body workouts. Users can view details such as minutes listened and changes in heart rate on the Apple Health app dashboard.

The app offers different modes to match users' wellness goals: CALM for relaxation and stress reduction, FOCUS for increased productivity, SLEEP for deep sleep preparation, and ENERGIZE for boosting energy levels. VIBE uses an emotional assessment grid to measure users' emotional states before, during, and after each session, helping the AI personalize music for their wellness goals. Users can track their mood-state results over time in post-session charts.

VIBE Premium offers a 7-day trial of all premium features and modes. After the trial period, users can choose a monthly or yearly subscription for the Premium modes (Calm, Sleep, Focus, Energize).
